The fast progression of wireless technologies has motivated the emergence of new communications system called VANETS (Vehicular Adhoc Networks). VANETS enable
vehicles on the roadway to communicate with each other and with road infrastructure using
wireless capabilities. The applications of VANETS include improving safety and comfort
on the road. For example, by providing Internet to vehicles, traveling can be safer and more comfortable. To provide Internet connectivity, messages need to be exchanged between the vehicles. However, it is hard to design an efficient routing protocol for connecting vehicles to Internet with a reasonable cost due to high mobility in VANETS.
Although, several existing routing protocols have been proposed in the open literature to
extend Internet to VANETS, they generate considerable overhead. This leads to unfairly
consumption of bandwidth decreasing network performance.
We design a routing protocol to connect vehicles to Internet through mobile gateways
with the objective to make efficient use of the network bandwidth. Indeed, the protocol
significantly reduces the communication overhead required to establish and maintain the routes relying on the mobility of the gateways and the network’s load.
